“…In their analysis, they have included the heat transport effect and fluids flowing through porous media affected by an axial electric field. Han 29 implemented the viscous potential flow theory to study the interface of two nanofluids in a planar channel. Moatimid et al 30 considered the stability of the swirling annulus of the nanofluid and viscous fluid interface.…”

The interface of a viscous fluid and [Formula: see text]-water nanofluid is analyzed through linear instability analysis in a spherical configuration. The viscous fluid lies inside the sphere while the outside region contains nanofluid. In this model, the viscosity of the nanofluid is considered a function of the base fluid viscosity, nanoparticles volume fraction, fractal aggregates, and nanoparticles shape. The perturbed flow is taken as irrotational, and the linear perturbation equations are solved through viscous irrotational theory. The perturbations growth rate can be computed through a 2-degree polynomial and the coefficients of this polynomial are the functions of the Atwood number, Richardson number, Weber number, Reynolds number, etc. The nanofluid interface is found more stable than the viscous fluid interface. The density of nanofluids raises the amplitude of disturbances while the nanofluid's viscosity has a reverse effect.

This study deals with the instability of shear waves, also known as Kelvin–Helmholtz instability, propagating with a complex frequency ”ω” in magnetically quantized dense gyro-viscous plasmas. The instability arises from the transverse spatial shear of the streaming velocity, which evolves from the DC electric and magnetic fields. In dense plasmas, quantum effects contribute through magnetically quantized statistical Fermi pressure, tunnelling potential and exchange-correlation potential. The contribution of the shear profile, the drift velocity, the number density of medium species, the dc magnetic field and the propagation angle θ of the wavevector on the instability is pointed out analytically as well as graphically. By varying the angle, shear size and density of plasma particles, the growth rate is enhanced. It does not, however, change as the streaming speed increases. This work seeks applications to study the characteristics of complex media like astrophysical and semiconductor plasmas [R. P. Drake, “Hydrodynamic instabilities in astrophysics and in laboratory high-energy–density systems,” Plasma Phys. Control. Fusion, vol. 47, p. B419, 2005].
